Abstract

Digital communication based on memristors is a new field. The main principle is to construct a modulation and demodulation circuit by using the resistance variation characteristics of the memristor. Based on the establishment of the Knowm memristor simulation model, firstly, the modulation circuit is designed by using the polarity and symmetry of the memristor and combined with the commercial current feedback amplifier AD844. It is proved that the modulated signal based on the memristor is a strong function of phase, and the demodulation circuit is designed accordingly. All simulation circuits are based on the actual commercial physical device model. The analytical expression of the output signal of the modulation and demodulation circuit is deduced theoretically, and the communication performance of the whole system is simulated by LTSpice. At the same time, the influence of the parasitic capacitance of the memristor on the circuit performance is also considered. After the simulation verification, the hardware circuit experiment of the modulation and demodulation circuit is carried out. The waveforms of the modulated signal and the demodulated signal are measured by an oscilloscope. The experimental results are completely consistent with the simulation and theoretical results.

摘要

基于忆阻器的数字通信是一个新领域。其主要原理是利用忆阻器的电阻变化特性构建调制和解调电路。基于所建立的Knowm忆阻器仿真模型，首先，利用忆阻器的极性和对称性并结合商用电流反馈放大器AD844设计调制电路。结果表明，基于忆阻器的调制信号是相位的强函数，并据此设计了解调电路。所有仿真电路均基于实际的商用物理器件模型。从理论上推导了调制和解调电路输出信号的解析表达式，并通过LTSpice对整个系统的通信性能进行了仿真。同时，还考虑了忆阻器的寄生电容对电路性能的影响。经过仿真验证后，进行了调制和解调电路的硬件电路实验。用示波器测量了调制信号和解调信号的波形。实验结果与仿真和理论结果完全一致。
